– Geopolymer concrete is an effective alternative to reduce adverse impacts of cement manufacturing on environment and achieving sustainable development. Road construction a major sector, which utilizes in large volume, having significant effect environment. The present work presented two parts. In the first part, evaluation CO 2 emission for 1m 3 geopolymer ordinary Portland has been carried o...

Geopolymer concrete that has polymer formwork is very likely to be used as reinforced material with several advantages. The advantages of geopolymer when compared portland cement are: resistant acidic environments (corrosion resistance), better bond strength reinforcement material, stable at high temperatures, higher fracture energy. Previous experimental studies found the tensile strength, and...

Abstract Geopolymer (GP) has recently emerged as a novel and environmental friendly alternative to conventional soil stabilization products like lime Ordinary Portland Cement (OPC), which adversely affect the environment. This article emphasizes GPs produced from high calcium class C fly ash (CFA) an alkali activator comprising sodium hydroxide silicate solution for sand stabilization. The expe...

This work aims to shape a hollow cylinder with geopolymer and an additive manufacturing process (3D printing) without organic additives. The formulation of composite using only mineral parts is proposed the parameters 3D printing were optimized. mechanical properties, microstructure, adhesion layers material analysed compared literature. results showed that could be printed addition small ratio...
